Specification of Letters Patent.

Application filed March 12,1906. Serial No. 305,491.

To all whom it may concern.-

Be it known that I, GEORGE T. REIss, a citizen of the United States, residing at Hamilton, Butler county, Ohio, (post-ofiice address care Niles Tool Works Company, Hamilton, Ohio,) have invented certain new and useful Improvements in Tool-Holders for Lathes, of which the following is a specification.

This invention, relating to tool-holders for lathes, will be readily understood from the following description, taken in connection with the accompanying drawings, in which Figure l is a side View, and Fig. 2 a rear view, of a tool-holder embodying my invention.

In the drawings, 1 indicates the base portion of the tool-holder, to be formed with or secured to any ordinary suitable tool-rest; 2, the tool resting thereon; 3 a pair of ears rising from the base portion and straddling the tool, the distance between the ears being greatly in excess of the thickness of the tool 4, a mortise extending horizontally through i each earabove the level of the top of the tool;

5, a nut-bar engaging these mortises 6, a set-screw threaded vertically through the nut-bar, and 7 a block whose presence is merely preferable in some cases between the top of the tool and the foot of the set-screw.

The tool in being set may be shifted sidewise out of center with the tool-holder either squarely or angularly, and whatever may be the sidewise position of the tool the nut-bar may be shifted endwise, so that the set-screw may come squarely over the tool.

I claim In a tool-holder for lathes, a base portion on which the tool may rest, ears projecting upwardly therefrom and'horizontally mortised above the tool-top level, a nut-bar engaging and horizontally shiftable in the mortises, and a set-screw vertically threaded into the nut-bar.
